Pgtented Apr. 7, 1931 UNITED STATES PATENT 4oEFlcE ARTHUR E. MILLER AND CHARLES H. JOHNSON, F SACRAMENTO, CALIFORNIA INCINERATOR Application filed January 9, 1929. Serial No. 331,297.

This invention relates to incinerators,'and especially to an incinerator adapted for use in automobiles and like vehicles.

The object of the present invention is to 5 generally improve and simplify the construction and operation of incinerators; to provide an incinerator which is particularly adapted for installation anduse lin automobiles7 motor buses, street cars and like vehicles; to prow vide an incinerator which is only intended to receive and consume suchobjects as cigar and cigarette butts, matches, bits of paper and the like, and which willinsure complete combustion thereof; to` arrange and position the incinerator in such a position on a vehicle that sucient draft will be maintained when the vehicle is traveling to blow or carry away the ashes; to provide an incinerator which will avoid all lire danger; and further to provide an incinerator which is operable whether the vehicle is traveling in one direction or another, for instance on street cars 'or the like which do not turn around when the end of the line is reached.

The invention is shown by way of illustration in the accompanying drawings, in which:

Fig. 1 is a partial section of an automobile showing the manner in which the incinerator is installed,

Fig. 2 is a perspective view partially in section, showing the housin of the incinerator and the tube through w ich the material to be incinerated should be delivered,

Fig. 3 is a perspective view of the incinerator proper which is removable with relation to the main incinerator housing,

Fig. 4 is a central cross section of the incinerator.

Referring to the drawings in detail, particularly Figs. 1, 2 and 3, A indicates the interior of an automobile, 2 the front seat, 3 the dashboard and 4 the windshield. Disposed below the oorboards of the auto- 45 mobile, 'and suitably secured to the main fra-me, or any part thereof, is an elongated housing generally indicated atB. This housing will hereinafter be referred to as the main housing of the incinerator. The housing is provided with an upwardly projecting tube rugated plate and the o 5 which is expanded at the upper end, as indicated at 6, the tube 5 may be disposed at one side of the vehicle or it may be placed wherever it is convenient to the occupant of the automobile. The expanded upper end of the tube carries a pair of valves, such as indicated at 7 and 8. These valves are pivotally secured to the Haring sides of the tube, as indicated at 9, and they are balanced so as to normally maintain the closed position shown in Fig. 2. The two valves are dis-' The housing B is substantially square in cross section. a pair of side plates 12 and 13, and a bottom plate 14. The ends of the housing are flared, as indicated at 15, and they are open so that vair may enter at one end and discharge at the I Y opposite end as will hereinafter be described. The incinerator proper is removable with re- It consists of'a top plate 11',

lation to the main housing B, either through the open ends of the housing, or through the side as will hereinafter be described. The incinerator proper consists of a bottom plate 16, a pair of side plates 17 and 18. Disposed centrally of the bottom plate, or intermediate the ends thereof, is a corrugated plate 19, and disposed intermediate said corposite ends of the incinerator are a series o inclined baiile plates.

-The plates shown at 20, and 21 extend from the bottom plate 16 to a point adjacent the top, while the plates shown at 22 and 23 extend fromthe top edge ofthe side plate 17 to a point adjacent the bottom plate.` These baflles serve two main functions, first that of y directing air over and under the corrugated plate 19, soas to insure combustion of waste matter deposited thereon, and secondly to prevent the escape of burning waste matter.

If the vehicle is traveling in the direction of arrow a, see Fig. 3, air will enter the incinerator in the direction of arrow b. It will pass over the first baille plate 20 and will then travel down and under the plate 22. It will then travel upwardly over the plate 21, and` then downwardly and under the plate 23, as indicated by the arrows. Air is thus directed under and over the corrugated plate 19, and if this contains a glowing cigar butt or the like, the draft will insure complete combustion thereof. rllhe products of combustion, together with the air entering between the baille plates 20, 21, 22, and 23 escape in a similar manner over andunder the draft will be strong enough to carry away the ashes.

It sometimes happens that persons riding in an automobile are more or less careless about disposing of waste xmaterial. For instance, they might discard or deposit articles which are not combustible. Such articles when deposited in the combustion chamber would gradually accumulate, and it is accordingly necessary toprovide means for re-y moving the incinerator proper from the main housing B so that such matter may be removed from time to time. AThe incinerator shown in Fig. 3 may be inserted or removed through either of the open ends of the housing B, and when so inserted may be secured by a pair of clamping screws such as indicated at 25. In some makes of automobiles it is possible that obstacles may be encountered which may make it dificult to insert or remove the incinerator with relatin to the main housing from one or either of the ends. In that case, one side or another of the main housing might be open, as shown in Fig. 2.

The incinerator proper could, in that instance, be inserted through the opened side and then secured by the screws 25.

In Fig. 1 the incinerator as shown is comparatively small and short. But if it is desirable to provide a waste receptacle or tube such as shown at 5 with relation to the rear seats of the automobile, it is obvious that the housing B may be elongated, or a second housing inserted.

On street cars, railroad coaches, etc., it might be desirable to employ a comparatively long housing, and to provide one or more incinerating compartments such as shown in Fig. 3. In that case, a number of upwardly projecting tubes with a valve at the top would be provided. In any installation, particularly Aon street cars and railroad coaches, it is essential that the baille plates be inclined and opposed to each other, as shown in Fig. 3 as street cars and coaches are usually designed to travel in either direction. That is, the street car may go to the end of the line, and return without turning around. In such a case the airi would enter the incinerator in the direction of arrow b when the street car was traveling in one direction, and it would enter in the direction of arrow c when the street car was traveling in the opposite direction. In either instance, the baille plates are arranged so that the air draft would be passed through in either direction without aifecting the efiiciency of the incinerator.

The corrugated bottom shown at 19 should preferably be employed whether the incinerator is long or short, as first of all it tends to maintain the material to be incinerated in a more or less elevated condition, and in the second place it prevents burning out of the bottom section, as air will pass freely under and over the corrugations. For instance, if a cigar butt drops on the corrugated plate and assumes the position shown at 27, see Fig. 4 it will be noted that the corrugations will support it in a more or less elevated po sition where air can pass under at a point indicated at 28, and also over and around the butt. This is advantageous as a sufficient supply of air is thus insured to promote and maintain combustion.

While certain features of the present invention are more or less specifically described, we wish it understood that various changes may be resorted to within the scope of the appended claims similarly, that the materials and finishes of the several parts employed may be suchas the manufacturer may decide, or varying conditions or uses may demand.
